3 Description

The LMC6482 device provides a common-mode

range that extends to both supply rails. This rail-to-rail

performance combined with excellent accuracy, due

to a high CMRR, makes this device unique among

rail-to-rail input ampliers. The device is an excellent

choice for systems, such as data acquisition, that

require a large input signal range. The LMC6482 is

also an excellent upgrade for circuits using limited

common-mode range ampliers, such as the TLC272

and TLC277.

Maximum dynamic signal range is provided in low

voltage and single supply systems by the rail-to-rail

output swing of the LMC6482. The rail-to-rail output

swing is maintained for loads down to 600 of theΩ

device. Specied low-voltage characteristics and low-

power dissipation make the LMC6482 a great choice

for battery-operated systems.

The LMC6482 is available in 8-pin PDIP and SOIC

packages. The device is also available in a VSSOP

package, almost half the size of a SOIC-8 device.

See the for a quad CMOS operationalLMC6484

amplier with these same features.

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may aect device reliability.

(2) If Military/Aerospace specied devices are required, please contact the TI Sales Oce/Distributors for availability and specications.

(3) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.

(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in

exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely

aect reliability.

(5) Do not short circuit output to V

+, when V+is greater than 13 V or reliability will be adversely aected.

(6) The maximum power dissipation is a function of T

J(max), RθJA , and T

A. The maximum allowable power dissipation at any ambient

temperature is PD= (TJ(max) −TA)/θJA. All numbers apply for packages soldered directly into a PC board.
